/* This is the main processing function for this program.
Arguments:
dbv - db pointer to a complex view of the database to be
processed. That is, it has these properties:
1. It is a join of:
event->origin->assoc->arrival
2. subset to single arrival name AND orid==prefor
3. sorted by evid/sta
pf - input parameter space
The main processing loop here keys on the grouping defined in the view
passed as dbgrp. That is, seismograms for each event group are processed
as a complete gather. After that, are nested loops to do the multiwavelet
processing as described in Bear and Pavlis (1999a,b).
